Description

Technical Field

[0001] The utility model relates to the technical field of climbing equipment, in particular to a climbing device and a roasting furnace. Background Art

[0002] The open anode baking furnace is the main equipment for baking anodes. During the baking stage, raw anodes are usually placed in the baking furnace for high-temperature baking. The baking furnace is mainly composed of multiple continuous furnace chambers. One furnace chamber can usually stack multiple raw anodes. During the placement of raw anodes, since each raw anode needs to be covered with a layer of filler to separate the raw anodes, personnel need to enter and exit the baking furnace to compact the filler and adjust the position of the raw anodes.

[0003] Since the floor area of ​​the furnace chamber is relatively small, basically every time a raw anode is laid, a person needs to enter and exit the furnace chamber once. Moreover, since the depth of the furnace chamber is relatively deep, about 3 to 5 meters, a ladder is usually set up on the inner wall of the furnace chamber to facilitate personnel to enter and exit the furnace chamber. However, the existing ladder is usually a straight ladder structure. The ladder of this structure is usually set up in an inclined manner with one end against the inner wall of the furnace chamber and the other end against the ground of the furnace chamber. Not only is it limited by the space in the furnace chamber, but it is also easy for the straight ladder to fall down due to sliding between the straight ladder and the inner wall or ground of the furnace chamber, which leads to a lack of effective safety protection when the straight ladder is used, and safety accidents are prone to occur.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0031] It should also be noted that the climbing device 100 of the utility model is not only applicable to the field of roasting furnaces, but also to other technical fields that require the use of tools to achieve climbing. That is to say, the climbing body used for the climbing device 100 to be erected can be the furnace wall 310 of the furnace chamber 300 of the roasting furnace, or it can be a wall or other structure. For the convenience of description, the following text will explain in detail using the application of the climbing device 100 to a roasting furnace as an example.

[0032] Combination Figure 1 and Figure 7As shown, an embodiment of the utility model provides a climbing device 100, including a ladder body 1, a connecting structure 3 and a supporting structure 4; the connecting structure 3 is connected to the ladder body 1 and is used to connect to the top of the climbing body; the supporting structure 4 is connected to the ladder body 1 and / or the connecting structure 3, and abuts against the climbing body when in use to form a support between the ladder body 1 and the climbing body.

[0033] Specifically, the ladder body 1 can be a straight ladder structure or an open ladder structure as described later, which is not specifically limited here. The connecting structure 3 is usually provided at the upper end of the ladder body 1, which can be a structure similar to a hook or a Figure 1 The inverted L-shaped rod structure shown in the figure is used to connect with the top of the climbing body, and the climbing body in this embodiment is usually the furnace wall 310 of the furnace chamber 300 of the open roasting furnace. Among them, when the connecting structure 3 is a hook structure, the top of the furnace chamber 300 is usually provided with a structure such as a fixing seat adapted to the hook structure, and the connection between the climbing device 100 and the top of the furnace chamber 300 is achieved by the mutual cooperation between the hook structure and the fixing seat. When in use, the connecting structure 3 is hung on the top of the furnace wall 310 of the furnace chamber 300 to hang the climbing device 100 on the furnace wall 310, so as to facilitate personnel to enter and exit the furnace chamber 300 through the climbing device 100. Among them, when the open roasting furnace is provided with one furnace chamber 300, the furnace wall 310 refers to the inner side wall of the furnace chamber 300. When the open roasting furnace is provided with multiple furnace chambers 300, two adjacent furnace chambers 300 are separated by a furnace wall. At this time, the furnace wall 310 refers to the side wall of the furnace wall located in the furnace chamber 300. The support structure 4 can be arranged on the connecting structure 3, or on the ladder body 1, or on both the connecting structure 3 and the ladder body 1. When the support structure 4 is arranged on the ladder body 1, the support structure 4 can be arranged at the upper end, middle part or lower end of the ladder body 1. In practical applications, in order to improve the stability of the support, it is usually preferred that the support structure 4 is arranged at the upper end of the ladder body 1. When the support structure 4 is arranged on the connecting structure 3, the support structure 4 is usually arranged at one end of the connecting structure 3 connected to the ladder body 1, and is located below the end. When the support structure 4 is provided on both the connection structure 3 and the ladder body 1, the portion of the support structure 4 provided on the connection structure 3 is usually the first support portion 41 described later, and the portion of the support structure 4 provided on the ladder body 1 is usually the second support portion 42 described later. Regardless of the arrangement, the support structure 4 is provided to abut against the furnace wall 310 of the furnace chamber 300, so that a certain distance is reserved between the ladder body 1 and the furnace wall 310, so that it is convenient for people to grasp the ladder body 1 for climbing.

[0034] The climbing device 100 in this embodiment can be set up by arranging a connection structure 3 on the ladder body 1 for connecting with the top of a climbing body such as the furnace chamber 300 of a roasting furnace, so that the climbing device 100 does not need to be set up in a tilted manner against the side wall of the climbing body when in use, but can be set up in a manner of hanging on the climbing body, which not only makes the climbing device 100 less susceptible to site restrictions, but also prevents the climbing device 100 from tipping over, effectively improving the safety of the climbing device 100 when in use. Moreover, by arranging a support structure 4 on the ladder body 1 and / or the connection structure 3, and making the support structure 4 abut against the climbing body, on the one hand, a certain distance can be reserved between the ladder body 1 and the climbing body, which is convenient for people to grasp the ladder body 1 for climbing, and on the other hand, it can provide support for the ladder body 1, thereby further improving the stability of the climbing device 100 when hanging on the climbing body and the safety when in use.

[0035] Optionally, combined Figure 1 As shown, the ladder body 1 comprises a ladder bar 11 and footrests 12 , and the footrests 12 are alternately arranged on both sides of the ladder bar 11 along the extending direction of the ladder bar 11 .

[0036] It should be noted that the ladder rod 11 is arranged in the vertical direction (ie Figure 1 The extension direction of the ladder bar 11 is set in the Z-axis direction, so the extension direction of the ladder bar 11 is the up and down direction, which is also the length direction of the ladder bar 11.

[0037] Specifically, the ladder body 1 is mainly composed of a ladder rod 11 and a plurality of footrests 12; wherein the ladder rod 11 is generally a columnar structure, which can be a columnar structure of a cylinder, a prism or other shapes; the footrest 12 can be Figure 1 The steel tube structure shown in the figure may also be a plate-like structure similar to a pedal, or other structures. In practical applications, in order to simplify the structure and facilitate manufacturing, steel tubes are usually preferred as footrests 12. A plurality of footrests 12 are provided on the left and right sides of the ladder bar 11. At the same time, the footrests 12 on the left side of the ladder bar 11 and the footrests 12 on the right side of the ladder bar 11 are alternately and spaced in the length direction of the ladder bar 11, that is, one end of the footrest 12 is connected to the ladder bar 11, and the other end is suspended. In other words, the ladder body 1 is roughly an open ladder structure.

[0038] In this embodiment, the footrests 12 can be alternately arranged on both sides of the ladder rod 11 so that the ladder body 1 can be roughly an open ladder structure, which is not only simple in structure and easy to manufacture, but also convenient for hanging, for example, a safety rope 2 and adjusting the height of the safety rope 2.

[0039] Furthermore, an anti-slip structure is provided on the footrest 12. The anti-slip structure may be an anti-slip protrusion provided on the footrest 12, or an anti-slip cover provided on the footrest 12, or other structures capable of achieving an anti-slip effect, which are not specifically limited here. This arrangement reduces the probability of slipping during climbing, thereby further improving the safety of the climbing device 100 when in use.

[0040] Furthermore, if Figure 6 As shown, in order to further improve the safety of personnel during climbing, the climbing device 100 may also include a safety rope 2, one end of which is sleeved on the ladder bar 11 and can be passed around the footrest 12 along the extension direction of the ladder bar 11, and the other end of the safety rope 2 is used to connect to the worker. Specifically, one end of the safety rope 2 can be tied into a ring knot and sleeved on the ladder bar 11, and then the other end of the safety rope 2 can be wrapped around the waist of the worker. In this way, the safety rope 2 can be hung at the connection between the ladder bar 11 and the footrest 12 under the action of the footrest 12, thereby playing a certain protective role. When the worker climbs up and down along the ladder bar 11, the safety rope 2 can be moved up and down by passing one end of the safety rope 2 with the ring knot around the outer end of the footrest 12, thereby adjusting the position of the safety rope 2 during the up and down climbing process, so as to further ensure the safety of the worker entering and exiting the furnace chamber 300.

[0041] Optionally, combined Figure 2 and Figure 7 As shown, the connection structure 3 includes a first connection section 31 and a second connection section 32 connected at an angle, and one end of the first connection section 31 away from the second connection section 32 is vertically connected to the ladder body 1, and the second connection section 32 is located below the first connection section 31 and is arranged opposite to the ladder body 1.

[0042] It should be noted that the ladder body 1 can be approximately a plane structure, specifically a plane formed by the center line of the ladder rod 11 and the center line of the footrest 12, and the first connecting section 31 is perpendicular to the ladder body 1, that is, perpendicular to the plane where the ladder body 1 is located. Figure 1 The center line of the pedal 12 is parallel to the Z axis. Figure 1 The Y axis in the figure, so the plane formed by the center line of the ladder bar 11 and the center line of the footrest 12 is Figure 1 YZ plane, that is, the first connecting section 31 of the connecting structure 3 is perpendicular to Figure 1 In other words, the first connecting section 31 is along the YZ plane Figure 1In addition, for a roasting furnace with one furnace chamber 300, the inner side of the furnace chamber 300 refers to the side located inside the furnace chamber 300, and the outer side of the furnace chamber 300 refers to the side located outside the furnace chamber 300; and for a roasting furnace with multiple furnace chambers 300, when the climbing device 100 is applied to a climbing operation of one of the furnace chambers 300, the inner side of the furnace chamber 300 refers to the inner side of the furnace chamber 300 currently performing the climbing operation, and the outer side of the furnace chamber 300 refers to the outer side of the furnace chamber 300 currently performing the climbing operation, and the outer side of the furnace chamber 300 may refer to the inner side of an adjacent furnace chamber 300. That is to say, when the climbing device 100 is erected, the ladder bar 11 is against the furnace wall 310 through the supporting structure 4, and the connecting structure 3 bypasses the top of the furnace wall 310 and extends into the outside of the furnace chamber 300 or into another furnace chamber 300 of the two adjacent furnace chambers 300.

[0043] Specifically, one end of the second connecting section 32 is connected to the first connecting section 31, and the other end is extended downward or obliquely downward. That is to say, the first connecting section 31 and the second connecting section 32 can be connected vertically, or connected at an acute angle or an obtuse angle, so that the connection structure 3 is generally L-shaped or L-like in structure as a whole; wherein, the L-shaped or L-like structure can be welded by welding or formed by bending. In practical applications, the connection form between the first connecting section 31 and the second connecting section 32 can be selected and designed according to the specific structure of the upper end of the furnace wall 310 of the furnace chamber 300. For example, if the upper end of the furnace wall 310 is a vertical plane perpendicular to the floor of the furnace chamber 300, the first connecting section 31 and the second connecting section 32 can be designed to be vertically connected. If the upper end of the furnace wall 310 is an inclined plane arranged at an acute angle to the floor of the furnace chamber 300, the first connecting section 31 and the second connecting section 32 can be designed to be connected at an acute angle. For the convenience of design and installation, it is usually preferred that the upper end of the furnace wall 310 is a vertical plane perpendicular to the floor of the furnace chamber 300, and the first connecting section 31 and the second connecting section 32 are vertically connected. When the first connecting section 31 and the second connecting section 32 are vertically connected, the second connecting section 32 can be arranged parallel to the ladder rod 11, or can be arranged at an acute angle to the ladder rod 11. In actual applications, in order to ensure the stability of the connection structure 3 erected on the top of the furnace wall 310, it is usually preferred that the second connecting section 32 is arranged parallel to the ladder rod 11.

[0044] In this embodiment, the first connecting section 31 of the connecting structure 3 is connected to the ladder bar 11, and is perpendicular to the plane formed by the center line of the ladder bar 11 and the center line of the footrest 12, and the second connecting section 32 of the connecting structure 3 is arranged below the first connecting section 31 and is arranged opposite to the ladder bar 11, so that the connecting structure 3 as a whole is roughly L-shaped or L-shaped. In this way, on the one hand, the structure of the connecting structure 3 can be simplified to facilitate production and manufacturing. On the other hand, the connecting structure 3 can be used to bypass the top of the furnace wall 310 and extend into the outside of the furnace chamber 300 or into another furnace chamber 300 of two adjacent furnace chambers 300, so as to hang the climbing device 100 on the top of the furnace wall 310, thereby realizing the erection and fixation of the climbing device 100.

[0045] Furthermore, in order to improve the service life of the climbing device 100 and the stability of the connection structure 3, a steel pipe of a fixed length is usually used as the first connection section 31. Moreover, the length of the first connection section 31 is usually slightly larger than the thickness of the furnace wall between two adjacent furnace chambers 300, so that a certain amount of erection margin can be reserved to facilitate the erection operation.

[0046] Optionally, the first connecting section 31 is a telescopic rod structure, which is used to adjust the distance between the second connecting section 32 and the ladder body 1 through telescopic movement.

[0047] In this embodiment, the telescopic first connecting section 31 is used to adjust the vertical distance between the second connecting section 32 and the ladder rod 11, wherein the first connecting section 31 can be an electric telescopic rod structure, a hydraulic telescopic rod structure, or a telescopic rod structure that uses a mechanical structure to achieve manual telescopic extension. In practical applications, since the climbing device 100 needs to be carried back and forth to different furnace chambers for use, it is usually preferred to design the first connecting section 31 to be composed of a threaded tube and a threaded rod with threaded matching, so as to ensure that the climbing device 100 is lightweight as a whole and easy to carry and transfer, so as to facilitate use back and forth in various furnace chambers; and when in use, the length of the first connecting section 31 can be changed by changing the length of the threaded rod screwed into the threaded tube to adapt to different furnace chamber spacing requirements, and the operation is simple and convenient. In this way, a telescopic rod structure is used as the first connecting section 31, so as to adjust the length of the connecting structure 3 of the climbing device 100 according to the thickness of the furnace wall 310 of different roasting furnaces, thereby improving the scope of application of the climbing device 100, so that the climbing device 100 can be applied to various types of roasting furnaces.

[0048] Optionally, combined Figure 1 and Figure 7As shown, the support structure 4 includes a first support portion 41, which is a plate-like structure and is located below the connecting structure 3, and two adjacent sides of the plate-like structure are respectively connected to the connecting structure 3 and the ladder body 1; and / or, the support structure 4 includes a second support portion 42, and the ladder body 1 is connected to the middle position of the second support portion 42, and the second support portion 42 is located on both sides of the ladder body 1 and is respectively used to abut against the climbing body.

[0049] In this embodiment, the support structure 4 has three configuration modes. The first mode is to only configure the first support portion 41. In this case, the first support portion 41 is generally a plate-like structure. The plate-like structure can be connected only to the first connection section 31 of the connection structure 3, or only to the ladder rod 11 of the ladder body 1, or to both the first connection section 31 and the ladder rod 11. For example, Figure 1 The example in which the adjacent two sides of the first support part 41 of the plate-like structure are connected to the first connecting section 31 and the ladder rod 11 respectively is given; the second is to set only the second support part 42; the third is to set both the first support part 41 and the second support part 42. When the first and third methods are adopted to set the support structure 4, the first support part 41 is not only located below the first connecting section 31, but also located on the side of the ladder rod 11 facing the furnace wall 310, that is, the first support part 41 is located in the area surrounded by the first connecting section 31 and the ladder rod 11. When the second and third methods are adopted to set the support structure 4, the middle part of the second support part 42 is connected to the ladder rod 11, and the second support part 42 is located on the left and right sides of the ladder rod 11 (that is, the ladder rod 11 is located on both sides of the Y-axis direction) for contacting with the furnace wall 310. In this way, under the support of the second support part 42 or the first support part 41, a distance is formed between the ladder bar 11 and the furnace wall 310 to facilitate people to grasp the footrest 12. In addition, the second support part 42 can be used to support the left and right sides of the ladder bar 11 to prevent the ladder body 1 from tipping over.

[0050] Optionally, combined Figure 2 and Figure 7 As shown, the second support portion 42 includes a first support segment 421, a second support segment 422 and a third support segment 423 which are connected in sequence, the second support segment 422 is cross-connected with the ladder body 1, the first support segment 421 and the third support segment 423 are arranged opposite to each other and are respectively located on both sides of the ladder body 1, and the ends of the first support segment 421 and the third support segment 423 away from the second support segment 422 are respectively used to abut against the climbing body.

[0051] In this embodiment, the first support section 421 and the third support section 423 are usually arranged on both sides of the ladder bar 11 where the footrest 12 is provided, and the structures of the first support section 421 and the third support section 423 can be the same or different. For example, Figure 1An example of a steel pipe structure in which the first support section 421 and the third support section 423 have the same length is given. In this way, the second support portion 42 is provided as a "C" - shaped structure formed by sequentially connecting the first support section 421, the second support section 422, and the third support section 423, so as to simplify the structure of the second support portion 42 and facilitate processing and manufacturing.

[0052] Optionally, in combination with Figure 1 and Figure 2 as shown, the climbing device further includes a fixing structure 5, which is provided on the ladder body 1 of the climbing ladder and is used to fix the rammer 200.

[0053] Since the staff needs to use the rammer 200 to compact the filling material in the furnace chamber 300, when the staff uses the climbing device 100 to enter and exit the furnace chamber 300, they need to carry the rammer 200 up and down while climbing, which is not only inconvenient but also likely to cause the rammer 200 to slip, posing a certain safety hazard.

[0054] Based on this, in this embodiment, a fixing structure 5 is provided on the ladder rod 11 of the climbing ladder body 1 to fix the rammer 200 to the ladder rod 11 by using the fixing structure 5. In this way, the staff does not need to carry the rammer 200 every time they enter and exit the furnace chamber 300, improving the convenience and safety of the staff entering and exiting the furnace chamber 300. Specifically, the fixing structure 5 is usually provided at the lower end of the ladder rod 11 to facilitate the staff to take the rammer 200 from the ladder rod 11 after reaching the bottom of the furnace chamber 300. The fixing structure 5 can be a snap - lock structure. At this time, the rammer 200 can be fixed to the fixing structure 5 by snap - connection to achieve the fixation of the rammer 200; the fixing structure 5 can also be a limiting member provided with a limiting groove. At this time, the two ends of the rammer 200 are respectively inserted and matched with the limiting member to achieve the fixation of the rammer 200.

[0055] Optionally, in combination with Figure 2 and Figure 3 as shown, the fixing structure 5 includes a first limiting member 51 and a second limiting member 52 that are spaced apart along the extending direction of the climbing ladder body 1. The first limiting member 51 is provided with a first limiting groove 511, and the second limiting member 52 is provided with a second limiting groove 521. The openings of the first limiting groove 511 and the second limiting groove 521 are arranged opposite to each other, and the first limiting groove 511 and the second limiting groove 521 are respectively used for inserting and matching with the two ends of the rammer 200. Among them, the extending direction of the climbing ladder body 1 is the same as the extending direction of the ladder rod 11, both being the Figure 1 Z - axis direction in

[0056] Specifically, the first limiting member 51 and the second limiting member 52 are usually arranged along the up - and - down direction (i.e., Figure 1The first stopper 51 is disposed at the lower end of the ladder rod 11 of the ladder body 1 (in the middle Z-axis direction), and the first stopper 51 is usually located below the second stopper 52. At this time, the notch of the first stopper 511 is disposed upward, and the notch of the second stopper 521 is disposed downward. Moreover, the structures of the first stopper 51 and the second stopper 52 can be the same or different. However, in actual applications, in order to reduce the number of parts and prevent assembly errors, the structures of the first stopper 51 and the second stopper 52 are usually designed to be the same. During the design, the first limiting member 51 can be fixed to the ladder bar 11 by welding, and the second limiting member 52 can be fixed to the ladder bar 11 by sliding connection. In this way, when fixing the tamping rod 200, the second limiting member 52 can be first moved upward by a certain distance to make the distance between the two limiting members greater than the length of the tamping rod 200, and then one end of the tamping rod 200 is inserted into the first limiting groove 511 of the first limiting member 51, and then the second limiting member 52 is moved downward until the other end of the tamping rod 200 is inserted into the second limiting groove 521. When the tamping rod 200 needs to be taken, the reverse operation can be performed. In this way, the tamping rod 200 can be taken and placed. The two limiters can also be fixed to the ladder bar 11 by welding. In this case, since the distance between the two limiters is fixed and smaller than the length of the tamping rod 200, the tamping rod 200 cannot be fixed by inserting it downward into the limit slot. Therefore, a notch needs to be provided on the side wall of the limit slot to insert the tamping rod 200 into the limit slot or move it out of the limit slot from the notch to realize the taking and placing of the tamping rod 200. In practical applications, the design can be selected according to needs, and no specific limitation is made here.

[0057] In this embodiment, a first limiting groove 511 and a second limiting groove 521 are respectively provided on the first limiting member 51 and the second limiting member 52, and the notches of the two limiting grooves are arranged relatively to each other, so that the upper and lower limiting members are respectively plugged into and matched with the two ends of the tamping rod 200 to fix the tamping rod 200 on the ladder rod 11 of the ladder body 1, thereby achieving fixation of the tamping rod 200, and the structure is simple and easy to process and manufacture.

[0058] Optionally, combined Figures 2 to 5 As shown, a first notch 512 is provided on the groove wall of the first limiting groove 511 , a second notch 522 is provided on the groove wall of the second limiting groove 521 , and the first notch 512 and the second notch 522 are arranged opposite to each other.

[0059] In this embodiment, the first notch 512 extends upward to penetrate the upper end of the first stopper 51, and the second notch 522 extends downward to penetrate the lower end of the second stopper 52, that is, the first notch 512 has edges only on the left and right sides and the lower end, but not on the upper edge, and the second notch 522 has edges only on the left and right sides and the upper end, but not on the lower edge. In other words, the first notch 512 and the second notch 522 are usually notch structures on the stopper, and are arranged opposite to each other. Moreover, as shown in FIG. Figure 5 As shown, the distance H1 between the first stopper 51 and the second stopper 52 in the vertical direction is usually smaller than the length of the tamping rod 200, and the distance H2 between the lower edge of the first notch 512 and the upper edge of the second notch 522 is usually larger than the length of the tamping rod 200. When fixing the tamping rod 200, the two ends of the tamping rod 200 can be aligned with the first notch 512 and the second notch 522 respectively, and then the tamping rod 200 can be pressed along the X-axis direction so that the two ends of the tamping rod 200 are respectively inserted into the first stopper groove 511 and the second stopper groove 521, so as to achieve the tamping rod 200 in the direction perpendicular to the plane where the ladder bar 11 and the footrest 12 are located. In this way, not only can the weight of the fixed structure 5 and even the climbing device 100 be reduced, but also the step of adjusting the second stopper 52 up and down can be omitted, thereby achieving the purpose of simplifying the steps of taking and placing the tamping rod 200, making it more convenient to take and place the tamping rod 200; in addition, the wear caused by adjusting the stopper up and down can also be reduced, thereby extending the service life of the fixed structure 5.

[0060] Optionally, combined Figure 3 As shown, the first stopper 51 is located below the second stopper 52, and the lower edge of the first notch 512 is located above the bottom wall of the first stopper groove 511. In other words, the size of the first notch 512 in the vertical direction is smaller than the depth of the first stopper groove 511 in the vertical direction.

[0061] In this way, after the lower end of the tamping rod 200 is inserted into the first limiting groove 511, it will fall a certain distance, so that the tamping rod 200 is restricted by the groove wall of the first limiting groove 511 located below the first notch 512, thereby preventing the lower end of the tamping rod 200 from falling off from the first notch 512; and when taking out the tamping rod 200, it is necessary to first lift the tamping rod 200 upwards for a certain distance and then take it out from the first notch 512, thereby improving the limiting effect of the limiting member on the tamping rod 200.

[0062] Furthermore, the upper edge of the second notch 522 may be located below the bottom wall of the second limiting groove 521, or may be flush with the bottom wall of the second limiting groove 521. In other words, the size of the second notch 522 along the vertical direction may be smaller than the groove depth of the second limiting groove 521 along the vertical direction. In this case, it is convenient to design the first limiting member 51 and the second limiting member 52 to have the same structure to reduce the number of parts; the size of the second notch 522 along the vertical direction may also be equal to the groove depth of the second limiting groove 521 along the vertical direction. In this case, the size of the second limiting member 52 along the vertical direction may be reduced, or the processing technology of the second limiting member 52 may be simplified to improve production efficiency.
